Materials and methods for constructing a block wall

Abstract

A construction block for use with other like construction blocks to build a retaining wall has a “bullet shaped” front with a pair of angled forward surfaces joining the front surface to the sides, and forming a 45° angle with the front and side surfaces. At least one hole is located in the front portion of the block, passing vertically through the block from the top through the bottom. The rear portion of the block is shaped to receive the front end of a corresponding block when two of said blocks are placed in a front-to-end orientation, and includes an indent defining a second hole extending through the block when two blocks are placed in a front-to-end orientation. Multiple front holes and multiple rear holes may be provided.
